Effects of nitrogen supply and drought on wheat grain quality under the ambient and elevated concentrations of carbon dioxide
Moravcová, Gabriela ; Vránová, Dana (referee) ; Hrstka, Miroslav (advisor)
This diploma thesis deals with effects of nitrogen supply, drought and UV radiation on wheat grain quality under the ambient and elevated concentrations of carbon dioxide. The theoretical part deals with the global climate changes, greenhouse gases and especially with effects of elevated concentrations of carbon dioxide on plants. Also, it is dealt with effects of elevated concentrations of carbon dioxide on the wheat grain quality. In the experimental part nitrogen content by the Kjeldahl method, contents of dry and wet gluten, Zeleny test, falling number and content of starch in the wheat samples were determined. The results of this study confirmed affecting the quality of the wheat grain from the elevated concentrations of CO2, nitrogen fertilization, drought and UV radiation. The most evident was the influence of nitrogen nutrition, fertilization positively affected the quality of grain, there was an increase in content of crude protein, gluten content, value of Zeleny sedimentation test, and falling number. As a result of the increase in protein content was also a decrease in starch content. Due to increased levels of carbon dioxide protein content and gluten, Zeleny sedimentation test values and falling number decreased and conversely starch content increased. The decrease of Zeleny sedimentation test by the influence of elevated CO2 concentration was fully compensated by nitrogen fertilization.

Climatological analysis of the Thaya river basin
Macík, Ondřej ; Kněžínková, Barbora (referee) ; Marton, Daniel (advisor)
The current climate changes and the persistent drought raise questions about the future development of temperatures and precipitation in the Czech Republic. One of the most affected area is south Moravia and the basin of River Dyje located there. The iam of this bachelor's thesis is to predict the future development of climate in the basin of River Dyje, using emission scenarios, a global climate model and an artifical time series Baseline by using a stochastic generator LARS-WG and subsequent analysis of the results. The obtained results will be suitably compared with each other and adjusted to the form for their future use.

Extreme hydrological events in the context of urban planning
Klimeš, Zdeněk ; Dráb, Aleš (referee) ; Duchan, David (advisor)
The purpose of the bachelor thesis was to describe known extreme hydrological events and potential attitudes to minimalize their negative impacts. The thesis was written as literature recherche from different points of view, not only from a one-sided technical or ecological point. It proceeds systematically from describing the historical evolution of the subject matter through the presentation of global ecological problems, outlining the legislative background and the findings from specialised literature, to the examples of current trends. In view of the fact that the issue is so broad, the thesis treats only certain parts in detail. The subject of interest is the demonstration of separate measures against floods and droughts and the effects of their synergy concerning the minimalization of the repercussions of extreme hydrological events.

Rainfall runoff process in time of climate change
Benáčková, Kateřina ; Janál,, Petr (referee) ; Marton, Daniel (advisor)
The aim of The Diploma Thesis was to compile a conceptual rainfall-runoff model, that would be eligible to model discharge in conditions of climate changes. After thorough verifications of possible variants, user program Runoff Prophet that is eligible to simulate discharge in closing profile of any river basin was compiled within this paper. Runoff Prophet is deterministic lumped model with monthly computation time step and from the hydrologic phenomena it takes soil moisture, evapotranspiration, groundwater flow and the watercourse flow into account. Its calibration is based on the differential evolution principle with Nash–Sutcliffe model efficiency coefficient as the calibration criterion. Developed software was tested on Vír I. catchment basin and the results of this probe were evaluated from viewpoints of air temperature, precipitation and discharge characteristics in the Dalečín measurement river cross section in distant future according to A1B SRES climate scenario, implemented in LARS-WG weather generator.

Generating of Stochastic Rainfall Data Using by Specific Weather Generator
Benáčková, Kateřina ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
The aim of this work is to study the topics of climate change, SRES emission scenarios, global GCM and regional RCM climate models, which are necessary basis for using the LARS WG software (Stochastic Weather Generator for Use in Climate Impact Studies). Based on given knowledge using LARS WG the testing time series of daily precipitation and temperatures data will be generated for three future time periods. The observed weather data from the Meteostation VUT was used. Generated data will be analysed and interpreted for its future uses.

Adaptation to climate change from the perspective of (Czech) law
Jech, Martin ; Sobotka, Michal (advisor) ; Fabšíková, Tereza (referee)
Adaptation to climate change from the perspective of (Czech) law Abstract Key words: climate change, adaptation, Czech law Climate change is a current topic that has an impact on many components of the environment and the whole society. Besides mitigation, adaptation is a key response to climate change. This diploma thesis deals with the issue of how (especially Czech) law approaches to adaptation to climate change. Particular legal instruments related to adaptation to climate change are discussed, especially conceptual, administrative and economic instruments, in the fields of protection of water resources, forest, agricultural land and nature and landscape. Selected non-law instruments related to adaptation to climate change are also mentioned. The thesis has several related research inquiries. The first question is what is actually a climate change and whether it is (or will be) its course unprecedented in the Holocene and the related question what climate is expected in the next decades. This is followed by other research questions, particularly how the political-legal approach to the question of climate change (especially adaptation) has evolved and what is the current legal level of adaptation to climate change, i.e. whether it is satisfactory or has some imperfections. And if it has some...

Interannual temperature variability in Europe
Švábek, David ; Huth, Radan (advisor) ; Mikšovský, Jiří (referee)
This master thesis is focused on interannual variability of air temperature throughout Europe and its long-term trends. Alongside changes in average air temperature, it is the changes in variability that fundamentally affect meteorological extremes. Therefore, those are fundamental climate characteristics at which we do not know yet if they are changing and if so, in what direction. The changes seem to differ between individual regions, seasons and timescales. Changes behave differently when they are short-term (interday to interseasonal) and when they are long-term (interannual). These interannual changes are the main topic of this master thesis. In the review part of the thesis, the scientific literature is summarized, supplemented by changes in interannual variability both globally and regionally for the territory of Europe, namely for individual seasons. The objective of the practical part of the paper is the analysis of long-term interannual temperature variability in the period from 1 March 1961 to 28 February 2018, for each season separately. The objective of this work is not only to quantify the trends of interannual temperature variability but also to compare them among five different climate databases, as most scientific studies that analyse long-term changes in variability have been...

Nature-based solutions and biomimicry for urban sustainability and climate change mitigation and adaptation: a case studies analysis
Hreljic, Aziz
This thesis reviews the role of nature-based and biomimetic solutions in improving the dimensions of urban sustainability and their effectiveness in addressing the growing pressures of climate change through mitigation and adaptation. The five case studies conducted on solutions in five cities from five continents suggest that the utilization of nature-based solutions in urban contexts creates benefits for all three dimensions of sustainability, albeit to different extents, despite the lack of policies that purposefully incorporate nature-based and biomimetic solutions in urban infrastructure. The study further revealed a lower level of usage of the solutions in climate change mitigation and adaptation, although there are some mitigation and adaptation co-benefits observed with some solutions. The economic dimension of development is undeniable, and from this perspective, there is still insufficient data that could be used to fully understand the implications and true value of nature-based and biomimetic solutions. This can also be said about quantitative data about the effects of the analyzed nature-based and biomimetic solutions in terms of air purification or energy efficiency. However, there is some data that implies these solutions support both energy efficiency, as well as bring environmental and health benefits to their users. Something that cities can and should do is develop policies that will promote the usage and monitoring of nature-based and biomimetic solutions in urban areas, in order to future-proof their infrastructure and to reap their social and economic benefits.
